Given numbers are 398,605,464,638

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 398,605,464,638 is 55863280.

Find LCM of 398,605,464,638 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 11 x 29 x 199 x 55 x 8 x 1 = 55863280

Therefore, the lowest common multiple of 398,605,464,638 is 55863280.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

398 x 605 x 464 x 638 = 71281545280

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

398 : 1, 2, 199, 398

605 : 1, 5, 11, 55, 121, 605

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,605,464,638, is 1.

Now, the common factors can be found like this.

398:2x 199

605:5x 11x 11

464:2x 2x 2x 2x 29

638:2x 11x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 11x 29 = 1276

Therefore, the value for common factors is 1276.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 71281545280/(1x1276)

LCM = 71281545280/1276

LCM = 55863280

Thus, we can understand that the LCM of 398,605,464,638 is 55863280.
